Abstract

Porous hydrophilic composites for use in promoting bone growth are disclosed, along with methods for their preparation. The composites comprise a porous biodegradable polymer matrix, and nanosized calcium phosphate (CaP) homogeneously dispersed throughout the polymer matrix. The CaP has a specific surface area in the range of about 180 to about 380 m<sup>2</sup>/g.
